Macbook Air A2179 2020 boot loop

[rlowe215]

Hello
Dont know what to do with this one. No sign of waterdamage. Boots to apple logo then shuts off and boot to logo again. Just looping.

Tryed recovery mode but nothing happens
internet recovery mode loads then shuts off before starting
Recovery from USB shuts down when loading

AHT no problems
Target disk mode works.

Save data in Target Disk mode (if important) and do DFU restore.
Revive not always helps.

Remove audio board and check for liquid sign on both sides.

Cant even get it to go to DFU mode =(

Did you exactly follow the steps from DFU tutorial?

 

[rlowe215]

yes

It appears as Recovery in AC2, or not recognized at all?

You can try forcing SOC_FORCE_DFU signal to 1V8_SLPS2R momentary.
Shouldn't need the charger for this; 5V from the other machine is good enough.
